That looks strange, but the process is the same as other absolute value equations You have to get everything except the absolute value part on one side of the equation. Then to get rid of the absolute value vertical bars, you set up two cases: one case is equal to what you have, and the other case is equal to the negative version of what you have. Typing here is a terrible way to try to explain the steps. there are a lot of fractions, to keep up with. I ended up getting 5/2 and 13/2 for x, and they both checked out. Wish I had a way to show the steps.

wow great! but whats the formula for that ? to be able to solve the equation?

It might help you to start with some very simple absolute value equations and work your way up. Basically, start with this question. What does $|x|=5$ mean? It gives you two solutions $x=5$ and $x=-5$.

Or, you can think of it like this; it means that $x=5$ or $-x=5$. It all goes back to the actual meaning of absolute value!
